Well it was actually Sunday, but had to wait till I had time to post.
I cleaned the corvette up after it's hibernation, then went to work on finishing the removable rear window conversion which is now down. I painted almost all the interior panels and pcs except for the console, which I will do this weekend.

Got the wiring diagrams from panamera. They are great! Hope I spelled his forum name correct.

I fitted the power steering belt that I bought from RockAuto. My first use of RockAuto and based only on that one item I was impressed. Ridiculously cheap compared to the same item for sale in Europe or the UK (my usual sources of supply) and very quick delivery by post.

Genuine AC Delco belt, so popped on with no issues and runs nice and quietly - so also fixes the odd noise issue I had!

Of course, I did notice that the alternator belt was a tad loose. Not the usual belt on mine for some reason, so not so easy to get hold of.....

Finished the drivers side suspension rebuild, new upper and lower ball joints, control arm bushings, tie rod ends and new springs. In order to torque the control arm end bolts I then removed the hood, fan, water pump pully, removed the top two radiator support bolts, loosened the lower side bolts and bottom bolts then rotated it forward enough too get the fan shroud out of the car. Finally I had enough room to torque the bolts!. Now that it's all back together next stop is the alignment shop.

Thought I had a fuel system problem when returning from a drive last weekend, Car was stumbling and had trouble getting up to speed and 5) mph max acting like bad fuel pump or filter.

Got some suggestions from my Vette doctor and did some trouble shooting first thing he suggested was accelerator cable, Turned out that the new accelerator cable had an improperly placed and crimped metal ferrel on the outer sleeve where the clamp attaching the cable to the carb bracket goes so the outer sleeve was moving in the ferrel to the point it only allowed 1/2" of throttle travel. When I popped the cable off the carburetor the cable end was an inch plus beyond the mounting point on the carb linkage. There was no way to adjust the ferrel at the clamp to make up the distance so I checked the sleeve and it moved inside the ferrel even though it appeared to be crimped. So I pulled the excess sheathing thru the ferrel and all was fine. You may want to check your cable if you don't have enough throttle travel before replacing or bending things. I'm glad I checked it before replacing the fuel pump, filter, sock or messing with the carb. Tim

Went to install the new Hayden fan clutch on my '69 coupe small block, and discovered that the prior owner had installed a complete clutch-free fan with the spacer integrated. I had hoped to keep the fan and remove the spacer.
But ended up installing a nice 6-blade aluminum fan with the new clutch. I kind of like the brighter look up front now.
Was a bit of a bugger getting it mounted on the pump pulley, as I was determined to use studs instead of just bolting the clutch flange to the pump. The studs wouldn't stay still enough for me to get all four nuts fully threaded. Had to try several times.
Late that night, lying in bed, I figured it out: pre-thread the nuts on the studs a sufficient amount before threading them onto the pump flange.
Oh well - next time I'll know better!

Looks great!
Are those new control arms as well?
Or did you have the originals refinished?
I contemplating that project for NEXT summer!

Original. I just cleaned and painted. I'm lucky that car has always been southern, no rust to contend with, just years of dirt and grease.

Last week: new carpets front & back

Friday evening: My 78 came with an older CD player that wouldn't read CD's, and missing the rear speakers and grilles. I Dropped by Best Buy and picked up a new pair of 4x6's for the dash, 6x9's and boxes for the rear, a new radio with bluetooth (so it'll play audio files right off my phone wirelessly), and tossed in a 10in Kicker and 600w mono amp just for the heck of it. Total spend was $500. I haven't tucked all the wiring in just yet, as I'm working through the best way to make the sub easily removable. The 6x9 boxes are pretty bulky, but I haven't decided whether I'm going to build my own, or just buy a pair of the tuck-away 6x9 boxes for back there. So these will work for now, while the design evolves. But I can crank Metallica without a hint of distortion, to the point that it drowns out my straight pipes.




Saturday: My headlights weren't being allowed to go all the way up, and the adjusters were too seized to work with in the tight space. So I removed both headlight assemblies, undercoated everything I could reach in there, disassembled and cleaned everything up, and put it back together with 4 new bulbs.

Looking good DB. I installed something similar in my '81. It turns my brain to mush. Especially with some Metallica playing.

Installed a new fuel pump (the C4 upgrade) in my '82. Getting it out wasn't actually that hard.. getting it back was another story. Not that the car was having issues, but I thought I would head off any potential issues before they start. But when I got in there, someone had already changed the OE pump at some point.. who knows when. But made my job way easier since the pump in there was plug and play, just like the replacement I had in my hand. Only "bubba" moment was trying to get the last bolt down putting the unit back in - the one up and behind the left return line.. It may be cross threaded.. oops...

Today, I pulled off the old rotten t-top weather strips, cleaned everything up nice, and got my new pair installed. Now there's nice fresh rubber all around the doors, door glass, and t-tops to keep the wet out. Woohoo ! Next time I get the itch to wash the car, I can turn the hose on it without fear of getting the interior all wet

The next round is a series of door projects... waiting on some dye and touchup paint to arrive. Once those are in hand, and I get my new set of rearview mirrors painted, I can pull the door panels and replace the felt window guides, put the new mirrors on, dye the lower part of the door skins to match the new carpet, install a new lock actuator in the passenger side and hook it up to the keyless entry, and replace my driver side outer door handle. Then when my neutral safety switch gets here, I can run my amp wiring underneath the console side panel while I have it off, and I'll have the backup lights working. Easy peasy

Yesterday (Sunday) we took the 73 for a nice drive over to Benicia which is on the east side of the San Fransisco Bay and walked through the annual car show that benefits the local high school. It was chilly with the breeze blowing off the water but there were several hundred cars in attendance. There were six C2s, two C3s and only one C1.

Drove the 76 big block with side pipes to pick up my 12 year old from school. Kids and parents thought it was awesome. Best compliment came when we drove up the street heading home, the wife was standing outside waiting to go for a walk. She said I looked so f@cking cool coming down the street. .
